Place bread in a 15-in. x 10-in. x 1-in. baking pan; bake at 300° for 15-20 minutes or until crisp. In a large skillet, saute cauliflower in butter with the caraway seeds until tender. Remove from the heat; stir in bread and cheese. Transfer to a greased 11-in. x 7-in. baking dish.
In a small bowl, whisk the eggs, beer, mustard, coriander and pepper. Pour over bread mixture. Bake at 350° for 30-35 minutes or until a knife inserted near the center comes out clean. Yield: 8 servings.
